Onion on sale is a how they sound like when they attempt to say annyeonghaseyo (안녕하세요) which is the formal word which means hello in Korean.

Person 1: onion on sale oppar, sarong hay

(Annyeonghaseyo oppa, saranghae)

Person 2: lmao your Korean sucks, you know oppa means older brother right..?

onion fart 

A fart that stinks so bad that it causes the eyes of those unlucky enough to smell it to tear up. Also known to be one of the densest of all farts- it takes about 5-6 minutes for the smell to dissipate.

Gross! Sammy just let out an onion fart!
